IMPROVEMENT IN HYDRAULIC RAMS.

Specification forming part of Letters Patent No. 200,081, dated February5, 1878; application iiled l November 3, 1877.

Ybe of any desired construction, and upon the top of which are placedthe two airchambers b d. These chambers are placed in a line with thelength of the frame, and have the flanges e formed upon their loweredges, so as to catch under the projections g, formed upon the top ofthe frame A. By placing a suitable packing under each chamber, a tightjoint is formed, and yet both chambers may be readily removed wheneverit may be necessary.

After the inflowing water has passed the maintaining-valve a it isimmediately under both chambers, and is acted upon by the air in both ofthem, in such a manner as to force the water forward and out through thedischarging-chamber d. The valvea is placed between the regulating-valvei and the receiving-chamber b, so that none of the Water may' escapebackward, and thus have its force lost.

- Where this valve is not used a great portion of the inrushing waterreacts, and thus fully one-half of its power is lost.

By the use of a receiving-chamber, b, and a discharge-chamber, d, agreat body of water may be raised by a very slight fall.

Having thus described my invention, I claiml. A hydraulic ram providedwith a receiving-chamber, b, and a discharge-chamber, d, substantiallyas shown.

2. In a hydraulic ram, the location of thev maintaining-valve a betweenthe receivingchamber b and the .controlling-valve t', substantially asset forth.
